Telkom - cancellation service non existent!

I'm trying to cancel my month to month subscription on my Fibre Home service since 28 November already. Every time I phone 10210 I get through to the sales department although I choose the right option. Then they have to put me through to the right department and very conveniently they are offline when they hear that I want to cancel my subscription! In other words, Telkom is ONLY online for people who wants new services from them, but for 3 days (28, 29 and 30 November) they are offline for all cancellations! I don't buy this nonsense. Pathetic client service. The client service consultants really need training on HOW to talk on a telephone and also on actually give a service! Don't subscribe to any service with them as you will definitely won't be able to cancel or change anything without a LOT of trouble.
